Origins of the seven-day week

The concept of a seven-day week has ancient origins, tracing back to the Babylonians around 1500 BCE. The Babylonians, keen astronomers, divided their lunar cycle into four weeks of seven days each, aligning with the phases of the moon. This practice was later adopted by the ancient Greeks and Romans, who found the seven-day cycle practical and meaningful.

The ancient Hebrews' influence also played a crucial role in establishing the seven-day week. According to the biblical account of creation, God created the world in six days and rested on the seventh, establishing a divine precedent for a seven-day cycle. This tradition was deeply ingrained in Hebrew culture and religious practices.

By the 1st century CE, the Romans had formalized the seven-day week, integrating it into their calendar system. This structure, combining astronomical observations and religious traditions, eventually spread throughout the Roman Empire and beyond, becoming the foundation of the modern seven-day week we use today.

In the Arabic and Hebrew calendars, the day begins at sunset, which contrasts with the Swahili concept of the day starting at sunrise and the Western world, where the day starts at midnight. This highlights the cultural influences on how days are numbered and identified within these different calendrical systems.

Origins of days of the week

How did Monday get its name? Meaning of Monday

Monday is named after the Moon. The Old English word for Monday was Monandæg, which translates to "Moon's day". This naming convention is quite common across various languages; for instance, in Latin, it's dies Lunae, also meaning "day of the Moon".  

Tuesday name origin

Tuesday is named after the Norse god Tiw (also known as Tyr), a god of war and sky. The Old English term Tiwesdæg directly reflects this association. The connection to Mars, the Roman god of war, can also be seen in other languages, such as French (mardi).

Why is Wednesday called Wednesday?

Wednesday is named after Odin (or Woden), the chief god in Norse mythology. The Old English Wodnesdæg translates to "Woden's day". This day is associated with Mercury in Roman mythology, which is why it's called miércoles in Spanish and mercredi in French.

Thursday name meaning

Thursday is named in honor of Thor, the Norse god of thunder. The term 'Thor's day' serves as the etymological basis for Thursday. In Old English, it was Þūnresdæg (Thunor’s day). The link to Jupiter, the Roman king of gods and god of thunder, explains the name jeudi in French and jueves in Spanish.

Friday history and meaning

Friday is named after Frigg (also known as Frigga or Freya), the Norse goddess associated with love and beauty. The Old English term Frigedæg means "Frigg's day". In Roman mythology, this day is linked to Venus, the goddess of love, which is reflected in names like viernes in Spanish and vendredi in French.

Saturday name origin

Saturday is unique among the English day names as it retains its Roman origin, specifically named after the Roman god Saturn, the Roman god of wealth and time. The Old English Sæternesdæg directly references this deity. Interestingly, in other Germanic languages, the name often refers to the Sabbath, such as Samstag in German.

Sunday - The sun's day

Sunday is named after the Sun. Icelandic uniquely retains 'only the Sun' as the name for Sunday, rejecting names derived from pagan gods. The Old English Sunnandæg translates to “Sun’s day”, reflecting its importance and reverence in various cultures. This name is consistent across many languages, highlighting the widespread significance of the Sun.

The importance of understanding day names etymology

Understanding the etymology of day names helps language learners grasp the historical context and deepens their appreciation of English. These names are more than just labels for days; they are windows into ancient beliefs, cultures and linguistic evolution. The influence of Greek and Latin names on the naming of the days of the week during the Greco-Roman tradition is particularly notable, as the classical planets from Hellenistic astrology played a significant role in this process.

Exploring the origins of the day names in English reveals a blend of mythology, history and language evolution. From the Moon to Norse gods to Roman deities, each name tells a story of cultural significance.

    How to improve your listening skills quickly
    By Charlotte Guest
    Reading time: 4 minutes

    Listening is an important part of learning a language. It helps you understand conversations, follow instructions and communicate with confidence. But listening can also feel difficult, especially when people speak quickly or use words you do not know.

    The good news is that you do not need to spend hours listening every day to improve. With the right practice, you can make progress in just a few minutes. Here are some ways to improve your listening skills quickly.

    1. Listen to something you understand

    Choose audio or video that is close to your current language level. If you understand almost nothing, it can be difficult to learn from it. If you understand every word, you may not be learning much.

    Start with short conversations, learner podcasts or videos with clear speech. You can also use social media content, including memes, short videos and posts in the language you are learning. These can be a fun way to see and hear everyday language without feeling like you are doing a formal lesson.

    For example, you could look at a meme in your target language and try to understand the joke before using a translation tool. Short videos can also help you hear common expressions and the way people speak naturally.

    Try to understand the main idea before worrying about every word. If you are learning English, you could listen to a short conversation about shopping, travel or daily routines. These topics are useful because you are likely to hear similar language in real life.

    5 team building activities to help break down boundaries
    By Anna Roslaniec
    Reading time: 4 minutes

    At the beginning of term adolescent learners are often shy, embarrassed and awkward. They are reluctant to speak English in front of their peers or show enthusiasm in class, often suffering from social pressure and lack of self-confidence. It can take weeks or months for students to get to know each other and form bonds. However, don’t despair if your teen learners are like this. There are plenty of team-building games and activities you can do to help students build relationships that will allow them to feel comfortable and relaxed in the classroom.

    Team building activities to help break down boundaries

    Why use team-building activities in the classroom?

    Team building activities can help:

    • Break down boundaries
    • Teens get to know each other
    • Build trust and teamwork
    • Bring 21st-century skills - collaboration, communication, critical thinking, and problem-solving skills - to life

    Team-building games can also be a lot of fun. They require students to work together to reach a common goal and sometimes include a competitive element, which can encourage teenage learners to get really involved. There is a wealth of different team-building games and activities suitable for older children and teens, but here we have chosen five that we think your teenage learners will love.

    1) Human knot

    In this fun physical activity, teamwork is essential. Students form a human knot, which they have to work together to untangle. It will also give you an idea of which students show leadership qualities.

    Materials needed: none

    How to play:

    Have students stand in a circle, making sure they are close together. If you have a large class, having students play in two or more groups may be better. The larger the group, the more complicated the puzzle will be. Tell students to reach across the circle with each arm and hold the hands of two other students. They can't choose the people standing on either side of them. Make sure students hold a left hand with their left hand, and vice versa. Now the human knot is formed.

    Tell students that they have to try to untangle the knot without dropping the hands they are holding. When they have successfully untangled the knot, students will be standing in a regular circle holding hands. Students will need to bend, twist, and move under or step over other students' arms.

    Tip: If one student is reluctant to play, give them the role of "director". This student can walk around the outside of the knot, giving instructions to help the group solve the problem.

    If you are doing this in groups, have them race against each other. The team to solve the problem first - wins.

    2) Magic carpet

    In this game, teams stand on a "magic carpet" which they have to turn over while still standing on it. Teams must decide on a strategy together and carry it out — if they try to do it individually, someone will inevitably fall off.

    Materials needed: rugs, towels, or large pieces of cardboard (one per team)

    How to play:

    Give each team their magic carpet and have them stand on it. Tell students they are on a magic flying carpet high in the sky, but there's a problem — the carpet is upside down. They need to turn the carpet over without anyone falling off.

    They need to devise a strategy for turning the carpet over without anyone touching the floor. Teams can work individually, or they can collaborate to help each other.

    The activity can be set up as a race to see which team flips their carpet first.

    Tip: Encourage students to rethink their strategy if it doesn't appear to be working. Evaluating your decisions and adapting your plan is a useful 21st-century skill that students can use throughout the school year.

    3) Build it

    Teenage students love a practical challenge; in this activity, the element of competition will undoubtedly get them involved. With just basic materials, students have to work together to build the tallest freestanding tower within a time limit.

    Materials needed: balloons (one pack per team), sticky tape, a tape measure, balloon pumps (optional)

    How to play:

    Have students form teams of four and hand out the materials. Tell students to build the tallest freestanding tower using just balloons and sticky tape in ten minutes. Explain that after ten minutes, you will check and measure the structures. If it falls over, that team is eliminated from the challenge.

    Tell students how much time is left after five minutes and again two minutes before the time ends. Have teams stand back from their towers. Inspect each tower, measure it, and record the results. You may wish to give the winning team a prize.

    Tip: Increase the challenge by giving students mixed bags of different-shaped balloons, including modeling balloons.

    4) My eyes, your eyes

    Students will have lots of fun guiding each other or being guided through an obstacle course by their teammates. This activity tests communication skills and builds trust between pairs of students.

    Materials needed: blindfolds or scarves (one per pair) and obstacles, e.g., chairs and boxes.

    Preparation: Before the activity, set up the obstacle course by placing furniture and other items around the classroom. Decide where the route students take will begin and end, marking the finish line.

    How to play:

    Put students in pairs. If possible, have them work with a student they don't know very well. Have one student in each pair cover their eyes with a blindfold. This student is a blinded person and their partner will be their eyes. The guide stands behind their blind partner and places their hands on their partner's shoulders. Their job is to quietly give instructions to guide their partner towards the finish line, navigating the obstacles. The first pair to finish wins.

    Have students swap roles. Move some of the obstacles. Then repeat the activity.

    Tip: If possible, play the game in the playground or in the school gym. The larger the space, the more complex you can make the route.

    5) Scavenger hunt

    This is a longer activity that requires slightly more planning than the others. Teams will complete a set of tasks and challenges as a race. Choose a mixture of fun challenges and serious tasks to turn this activity into a fun diagnostic test to determine students' English levels.

    Materials needed: Worksheet containing a list of tasks and challenges (one per team). Tasks can be both language-related and practical.

    How to play:

    Put students into teams. This activity is ideal for students with different skills and abilities, so try to ensure teams are mixed-ability. Tell students that they are going to race to complete a series of tasks that they will find on their worksheet. The fastest team to complete all tasks correctly wins. Some tasks can be completed by one student.

    Explain that students don't need to complete the tasks in order. Point out that you will monitor them closely to ensure there is no cheating. Remind students that they must use English at all times. You can choose to penalize students by having them repeat or do an extra task if they use L1.

    Tip: If you think students might try to cheat, before you set the teams, nominate students to be team monitors (one per team). They will have the worksheet and make sure that the team fulfills each task. Alternatively, if students have mobile phones or tablets, have them take pictures and videos of their team members completing the task.

    Do fast test results compromise accuracy and security?
    By Alice Bazzi
    Reading time: 2 minutes

    Speed is increasingly critical in global admissions. But with faster results comes an inevitable question: does speed compromise accuracy and security? 

    With traditional testing, long result timelines were often seen as a mark of thoroughness. Today, however, technology enables both speed and precision without any trade-offs. 

    PTE Express uses AI-powered scoring trained on large datasets of real tests responses, ensuring consistent and accurate evaluation across all candidates. Unlike manual grading, which can vary between examiners, automated scoring applies the same criteria to every response. In result, this reduces bias and increases reliability; two factors that are deemed as critical for high-stakes admissions decisions.
